Abstract
The invention discloses a fast test method for the glossiness supporting property of epoxy primer. The fast test method comprises the steps of (a) preparing test liquid, namely dissolving 28-32 parts of nitrocotton by using 100 parts of DL sec-butyl ester solvent, then adding 38-42 parts of epoxy resin, and stirring uniformly; (b) preparing epoxy primer to be tested according to the matching ratio of a main agent and a curing agent, carrying out blade coating on a coating film on a glass plate by using a wet-film preparer, putting into a drying box, and drying for 3-5 hours for later test; (c) carrying out blade coating on the test liquid on a sample plate to be tested by using the wet-film preparer, then putting the sample plate into the drying box with the temperature of 48-52 DEG C, drying for 25-35 minutes, taking out the sample plate and naturally cooling for 3-5 minutes; and (d) testing the glossiness of the sample plate, namely the glossiness supporting property of the epoxy primer to be tested. The fast test method has the advantages that the glossiness supporting property of the epoxy primer is tested by carrying out blade coating on self-drying test liquid on the epoxy primer to be tested, drying and measuring the glossiness, and the operation is simple, fast and accurate.
Description
Technical field
The present invention relates to a kind of epoxy primer holder oiliness method for rapidly testing.
Background technology
Often appear in epoxy anticorrosive paint when different priming paint spraying same finish paint and there will be different gloss, this performance holding finish paint gloss is called holder oiliness.The test of holder oiliness is as an important quality test index aborning.Holder oiliness that is how quick, easy, that test priming paint is accurately a difficult problem.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
For solving the problem, the invention provides a kind of quick, easy, the oiliness of epoxy primer holder accurately method for rapidly testing.
The technical solution used in the present invention:
Epoxy primer holder oiliness method for rapidly testing, comprises the following steps:
A, preparation test fluid: with the nitrocotton of the sec-butyl acetate dissolution with solvents 28-32 mass parts of 100 mass parts, the epoxy resin then adding 38-42 mass parts stirs evenly;
B, epoxy primer to be measured to be prepared according to host and hardening agent proportioning, use wet film preparing device blade coating film on a glass, put into dry 3-5 hour of drying box to be measured;
C, use wet film preparing device blade coating test fluid on model to be measured, be then placed on dry 25-35 minute in 48-52 DEG C of drying box by model, take out model and naturally cool 3-5 minute;
D, employing vancometer test sample plate gloss, this gloss is the holder oiliness of priming paint to be measured.
Described epoxy resin to be epoxide equivalent be 475 bisphenol A type epoxy resin, epoxy resin includes mass percentage 25% xylene solvent.
Described nitrocotton is nitrocellulose, and nitrocotton includes the ethanol of mass percentage 30%.
The invention has the beneficial effects as follows: by blade coating on epoxy primer to be measured from dry test fluid, after dry, measure the holder oiliness that glossiness tests priming paint, easy and simple to handle, fast, accurately.
